Cordovan posted on the forums about some upcoming downtime:
“The DDO Game Servers will be brought down on Monday, February 23rd from 9:00 AM – 12:00 PM Eastern (-5 GMT) for an update to the game. Thanks for your patience, and we’ll see you back in the game soon! Patch notes will be available during the downtime.”
We will be sure to have a post with the patch notes as soon as we can.
